NUT-PRESS.

SPECIFICATION forming part of Letters Patent N o. 737,724=, dated September 1, 1903.

, Application filed June 27,1902. Serial No. 113,899. (No model.)

To all whmn it may concern:

Be it known that I, THOMAS FERRY, a oitizen of the United States, residing at Cleveland, in the county of (Juyahoga and State of Ohio, have invented a certain new and useful Improvementin Nut-Presses, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

My invention relates to improvements in nutpresses; and it consists in the novel features of construction hereinafter described, reference being bad to the drawings, which illustrate one form in which I have contemplated embodying my invention, and said invention is fully disclosed in the following description and claims.

The object of my invention is to provide mechanism in connection with machines of the above-named class whereby the nut is punched, cut, shaped, and trimmed by the same machine. These operations take place in succession, but by one operation of the punching mechanism.

Referring to the drawings,Figure 1 is a nut. press shown in elevation and embodying my invention and having parts thereof broken away to more clearly show the same. Fig. 2

" is a side elevation of the same", showing the feeding mechanism and having parts broken away to show the hole punchingand cutting devices. Fig. 8 is a top plan view of the bedplate and the parts connected therewith. Fig. 4. is a top plan View of the die-plate.- Fig. 5 is a section on line so as of Fig, 3. Fig. 6 is a cross-section of a stock-metal guide; and Fig. 7 is across-section of the trimming-die, showing the nut in elevation.

Referring to the parts by letters, A represents the bed-plate, from which rise suitable standards B B, in the upper ends of which the crank-shaft O is mounted. A reciprocating cross-head E is mounted in suitable Ways F F on the standards B B and is connected with the crank-shaft by a connectingrod D. A driving-pulley G is mounted upon the shaft 0 and has in connection therewith clutch mechanism for operating the same.

Secured to the bed-plate in position for feeding the metal-stock strip are the feeding device and the oiling mechanism. This mechanism is of ordinary construction. It inratchet-wheel is operated by a link f pivoted l to an adjustable stud f carried by said arm f An eccentric-pin 0 projects from the end of the shaft 0, and the upper end of said link f is pivoted upon the same.

The foregoing description relates to the part of the machine which is old in the art, and the following description will relate particularly to my invention and the parts thereof.

On the bed-plate A, between guides at a, I secure a die-plate H, provided with suitable retaining-grooves h h, the inner faces of said guides being undercut, whereby the die-blocks may be held in place with the help of wedges. T-shaped guideways i 7; are also provided in said die-plate for receiving tongues on the under sides of the stripper-plate J, which is substantially of the form shown in Fig. 6, having guide-pieces jj secured to its under side by the screws j j, which pass through loose holes in said stripper-plate. The adj ustingscrewsj j are provided for carefully adjusting these guides jj. This stripper-plate also is provided with a hole 3' for the punch 11 to pass through. The dies are mounted in this die-plate H in the following manner: The punching-die M is wedged in the groove h, so that the opening in said die will register with an opening k in said plate, the opening in said plate being just slightly larger. than the opening in the die, so as to permit the metal punched out to pass down through the plate freely and at the same time leave sufficient support for said die. In advance of said die M is a cutting-off die N, also wedged in the groove h and so placed in relation to said punching-die M that the nuts will be out 01f properly with respect to the openings previously punched therein. Beneath this cutting-0d die N is the shaping-die N, which is secured in a hole in the plate h. This die has a vertical hole through which a plunger n operates.

Below the cutting-01f die N in the plate H is a runway n for a plunger O, which runway is the width of a nut. The plunger 0 is secured on the slide 0, which is so located that it will engage the lower end of the plunger 'n, and thereby liftit, whereby the nut in the shaping-die is lifted into the runway 01 in which the plunger 0 moves.

At right angles to the line of the punchingdieM and the cutting-off die N is a trimmingdie P, which is of the configuration shown in Fig. 7 and is secured in a groove 71 in the plate H, said die being so placed that a nut will be pushed onto it by the plunger 0.

Secured to the cross-head E are the respective punches-p, which is the punch to form the hole through the nut, p for cutting ofi, and 19 with its centering-point 20 for forcing the nut down through the trimming-die. Two guides Q Q are movably secured upon the plate H on either side of the die P, toward which they are moved by a spring Q until both are stopped by engaging with a distance-block. These guides are provided with wings q g, each of which has a slot g through which pass screws 11., which hold the guides down and guide them. The ends of these guides are beveled outward, so that a nut may be forced between them from the shaping-die N to the trimming-die P by the plunger 0. After the punch 19 has forced the nut through the' trimming-die P and has been raised to its upper position it leaves between the guides Q Q a shell, which is crushed by the pressure of the spring Q on thesaid guide.

The slide 0 is given a reciprocatory movement by a'lever R, fulcrumed at 'r' and having at one end a bifurcated portion 0", adapted to operate in connection with the friction-roller 0, carried by said slide, and at the other end a friction-roller 'r (Shown in dotted lines in Fig. 1.) This friction-roller r is adapted to operate in a cam-groove S in a cam-wheel S, and a spring Z acts on the lever to hold said roller against one face of said-cam-groove. On a line with the dies M and N is an adjustable stop T, projecting to the edge of the opening of the cutting-off die N and provided with a slot it, through which passes a setscrew for fastening said stop to the plate H.

The operation of the machine after it has been running for some time is as follows: As the cross-head descends a hole will be punched in the stock-strip by the punch 9, a nut will be cut off by the punch 10 and forced down through the die N into the shapingdie N, and a nut which was over the trimming-diePwill be forced down into the same to the position shown by dotted lines in Fig. 7, thereby trimming said nut and forcing out of said trimming-die the nut which was therein. When the cross-head goes up, the stripper-plate J prevents the punch 10 from lifting the punched stock-strip, the stock-feeding mechanism feeds the stock-strip forward against the stop-gage T, the plunger n lifts the shaped nut from the shaping-die, and the plunger 0 moves the nut between the guides Q Q to a position over the trimming-die, where it takes its place, resting for the time being upon the nut then in said die. The next down-and-up movement of the cross-head is accompanied by a repetition of the described operations, and the shell trimmed from the nut will be crushed by the guides Q Q, which are drawn toward each other when the punch is lifted from between them. As each nut comes into position over the trimming-die it pushes the trimming along toward the hole V, through which it falls. It will be understood that when the machine is first started the first three or four nuts cutoff will be without holes and must be thrown away.

Having described my invention, I claim- 1. In a nut-punching machine, the combination of a reciprocating cross-head carrying a plurality of punches, a cutting-off die, a shaping-die below it, a plunger movable upward through said shaping-die, a beveled slide operating said plunger and mechanism for operating said slide, and means connected with said slide for moving the nut, substantially as described.

2. In a nut-punching machine, the combination of a reciprocating cross-head carrying a plurality of punches, a cutting-0E die, a shaping-die below it, a plunger movable upward through said shaping-die, a beveled slide operating said plunger, a plunger secured to and movable with said slide, and adapted to move the nut to the trimming-die, and a trimming die, substantially as described.

3. In a nut-punching machine, the combination of a reciprocating cross-head carrying a plurality of punches, a cutting-off die, a shaping-die below it, a plunger movable upward through said shaping-die, a beveled slide operating in a suitable guideway below said shaping-die for raising and lowering said plunger, and another plunger connected with said slide for moving the nut along from said shaping-die, substantially as described.

4. In a nut-punching machine, the combination of a punchingdie, cutting-off and shapingdies, and a trimming-die with a reciprocating cross-head, three punches secured thereto, mechanism for feeding stock metal to the punchingdie and cuttingoif die, a plunger for removing the nut from the shaping-die, a slide having a beveled portion for operating said plunger, a second plunger secured to said slide for transferringthe nut to said trimming-die, and a single shaft for operating said cross-head and said plunger, substantially as described.

5. In a nut-punching machine, the combination with the bed, of standards secured to said bed, asingle shaft mounted in said standards, a cross-head operating between said standards, connections between said crosshead and said shaft, punches carried by said cross-head, a die-plate secured to said bed, a stripperplate in connection with said die said cam, said lever being adapted to operate said slide, a spring operating against said lever, and connections between said shaft and 15 the stock-feeding mechanism, substantially as described.

In testimony whereof I hereunto aflix' my signature in the presence of. two witnesses.
